New complexes of platinum (0) that contain N-heterocyclic carbene ligands

摘要

the subject of new platinum (0) complexes containing n - heterocyclic ligands karbenowe (nhc) of the general formula 1.where: n has the value 1 or 2 and r1 and r2 are the same and means: linear or branched alkyl groups from c1 to c4 or group or a group containing a group fenylowu0105 alkoksylowu0105 alkilowu0105 from c1 toc2 or br, cl.r3 means: group heteroarylowu0105 or arylowu0105 group containing 1 to 3 rings, r4 means: for n = 1: tetrametylodiwinylodisiloksan, 1,6 - heptadien,diallilomalonian diethyl ether or diallilowy and for n = 2: group dimetylofenylosililowu0105.the declaration also includes application of complexes of the general formula 1 in which n, r1, r2, r3 and r4 have the meaning given above as catalysts for reactions homodimeryzacji acetylenu00f3w and sililoacetylenu00f3w,hydrosililowania compounds containing multiple binding.
